Properly storing values passed in URL in Django - django

Question

I have the following URL:
http://localhost:8000/store/add/?points=5
I want to extract the number of points from my URL.
In my views.py, I have:
points = request.GET.get('points',0)
The problem is that it never finds points, so it uses the default of 0.
Any insight into what I'm doing wrong?
My urls.py
from django.conf.urls.defaults import *
from store.models import Part, Category, UniPart, LibraryRequest
from django.views.generic.list_detail import object_list
from voting.views import vote_on_object
urlpatterns=patterns('',
#/store/
url(r'^$','store.views.all_models',name="all_models"),
#/integer/view_part
url(r'^(\d+)/view_part/$','store.views.view_part',name="view_part"),
url(r'^your_models/$','store.views.your_models',name="your_models"),#/your_model
url(r'^user_models/(?P<username>\w+)/$','store.views.user_models',name="user_models"),
url(r'^add/(?P<points>\d+)/','store.views.add_model'),
Snipped from views.py:
def add_model(request, points=None):
print points

Answer 1

Well, your urls.py says that you should use following url /store/add/5, and in your views.py you need to have view
def add_model(request, points=None):
print points
If you want points as a GET parameter change your urls.py as following:
url(r'^add$','store.views.add_model', name='add_model'),
And then you can pass points as /store/add?points=5 and extract it from the URL as
points = request.GET.get('points')
UPDATE
Also in a future to avoid such problems I suggest you to add name parameter to your routes in urls.py (see above) and use reverse in your views (ex. reverse('add_model', kwargs={'points': 5}) and url in your templates (ex. {% url 'add_model' 5 %})
In that case all urls in your application will be generated automatically based on routes in your urls.py files.

Use the following code:
points = request.GET.get('points')
If you are passing more than one variable it can be done in two ways:
METHOD 1:
In your urls.py.
(r'^store/add1/?integer=(?P<category>\d+)/?string=(?P<keyword>\w+)$', 'view_function_name'),
You can get the above values in your views using the following:
def function_name(request):
int_value = request.GET.get('integer')
str_value = reuest.GET.get('string')
And you can also use the pattern given below:
METHOD 2:
In your urls.py.
urlpatterns = patterns('model_name.views',
(r'^store/add1/(?P<integer>\d+)/(?P<string>\w+)/', 'function_name')
)
In your views.py:
def function_name(request, integer= None, string = None):
print integer
print string
#Do whatever you wish with this value
The second method will be more easy for you.
